On another 32 bit machine with same 2.8 the web-app (Squirrelmail, or Poweradmin) runs fine. I am quite sure that the apps were runnig fine with DFly 2.6 installations although I am verifying it right now...

I attached a GDB backtrace for the gettext error of Poweradmin at the bottom of this e-mail. I recompiled PHP 5.2 with debug flags for gdb.

I am running the php interpreter with (newest) apache 2.2.16 and /usr/pkgsrc/www/ap-fastcgi module.
I first noticed it with PHP version 5.3.3 but when trying PHP 5.2.14 (and recompiling all dependencies) the same error occurs: The webserver says: Internal server error and the error_log shows:
